This is the first of four messages that Zechariah received from the Lord that bear on the question just raised. That there were four separate messages seems clear since each one begins with the same preamble: "The word of the Lord came"(7:4, 8; 8:1; 18). The first two, in chapter 7, are negative, and the last two, in chapter 8, are positive.
7:4-5 The Lord spoke to Zechariah, and he proceeded to inform the messengers, all the people in the land, and the priests. The issue that the messengers had raised had widespread implications for the whole nation. The Lord asked rhetorically if the people had really observed the fasts that they had instituted in the fifth and seventh months for 70 years for His benefit or for themselves. Seventy years is a round number for the length of the Captivity. The fast in the seventh month commemorated the assassination of Gedaliah (2 Kings 25:25; Jer. 41:2).148Evidently the people had turned these events into occasions for self-pity over their physical condition rather than engaging in prayer and genuine spiritual repentance.
7:6-7 Likewise when the people ate and drank they did it for themselves rather than to please the Lord. They were simply perpetuating the selfishness for which former prophets had rebuked their ancestors. The prophets in view had lived before the captivity when the whole land and its cities were still full of inhabitants (e.g., Isa. 58:3-9; Joel 1:14; 2:12). Now there were far fewer Israelites occupying the land. The Negev to the south of Beersheba and the foothills (Shephelah) toward the Mediterranean coast were grazing and agricultural areas in which the returnees had not yet settled.
"Note that the inquiry put by the Bethel committee is not being answered directly. In fact, throughout chapters 7 and 8 no direct answer is offered. The reason is: the question is not an important issue. However, the attitude revealed by that question is of sufficient moment to receive exhaustive treatment."149
